Understanding electrochemical potentials of cathode …
Figure 2.Schematic of the configuration of rechargeable Li-ion batteries. Na-ion, Mg-ion, or Al-ion batteries also have similar configurations, which differ from electrode materials , , .For a Li-ion battery, as illustrated in the figure, Li ions are extracted from the cathode and inserted into the anode during the charge process, and the reverse reaction occurs during the discharge process.
